Plate boundaries
Transform Boundaries
a place where 2 plates slip past each other moving in opposite directions. Earthquakes occur frequently along these boundaries.
Divergent Boundaries
Place where 2 plates more apart. Divergent Boundaries also occur on land, when they do 2 of Earth's plates side apart creating a rift valley.
Convergent Boundaries
place where 2 plates come together or collide. When 2 plates collide, the density of the plates determines which one comes out on top
